Name these charges



A is negative B is positive




Fill in the Blank Notes
Field Intensity and Distance



H) Field Intensity and Distance


1) Spherical point charge




Field intensity varies
 with the square of distance

Double distance from spherical charge,

the field intensity ....





is quartered




2. Charged Rod - the field intensity varies inversely with distance


If the distance to the rod is reduced to 1/3 its original distance,
the electric field intensity ...




would be 3 times greater
